Merge pull request #96 from phyloref/reviewable-changes

These are the reviewable changes from PR #89, which are primarily `regnum2phyx.js` changes:
- Improvements to how author names are rendered: we now support first-name first, last-name first, or last-name only.
- Generate scientific name authorship by using first-name first and combining them with " and ".
- Generate specifier authors by using last-name only and combining them with " and ".
- Added a CLI option to configure the number of digits in the `CLADO_` name, which now defaults to 7 instead of the previous 6.
- Modified the script to produce `CLADO_0000000` filenames instead of `REGNUM_0000000` filenames.

Two other minor changes:
- Added an optional test to ensure that Phyx files have at least one Newick phylogeny in order to see how many we have.
- Removed `phyloref_testcase.owl`, which was previously a copy of the phyloref.owl ontology we used to do reasoning.
